Package The LC5581AS and LC5581LS are quasi-resonant LED driver ICs.

The ICs can also operate in PWM mode.

The ICs support isolated and non-isolated buck circuits and buck-boost converters.

the ICs can provide more costeffective power supply systems with fewer external components. Features.
800 V High Voltage Built-in Startup Circuit.
Analog Dimming Function.
High Power Factor by Average Current Control.
Soft Start Function.
Shorter Time from Startup to LED Lighting.
COMP Pin Fast Charging Function.
Bias Assist Function that Includes Two Types that are Activated at Different Voltage Levels (Smaller Capacitance of the VCC Pin).
Standb.
